It looks like it's /usr/share/zoneinfo on all Ubuntu versions: alblue.local[~]$ docker run -it --rm ubuntu:14.04 find /usr -name zone.tab /usr/share/zoneinfo/zone.tab alblue.local[~]$ docker run -it --rm ubuntu:16.04 find /usr -name zone.tab /usr/share/zoneinfo/zone.tab alblue.local[~]$ docker run -it --rm ubuntu:16.10 find /usr -name zone.tab /usr/share/zoneinfo/zone.tab
This is the same that's coming from CFTimeZone.c: https://github.com/apple/swift-corelibs-foundation/blob/2611dcd0d9b91fecace537838294bd85f0220503/CoreFoundation/NumberDate.subproj/CFTimeZone.c#L36-L39 Is it possible that the MacOS header is being included and defining TZDIR before the CFTimeZone.c file is compiled?
